Amp Stands - Wood or Stone

I'm in the process of relocating my audio equipment to a side wall and need to place my amps, AGD Audions, on something.  Floor is carpeted.  Stands will be very small and won't be supporting much weight.  I have access to granite, marble, etc. (next to nothing scape from remodel jobs).  Also, have pretty good relationship with a serious wood worker who is happy to cut maple, oak, cherry, most any hardwood, etc.  Cost is not really an issue just looking for an opinion / logic around which material I should use.  At this point, I'm thinking 1 1/2 to 2 inch thick walnut on some kind of cone / spike legs. Sorry for maybe a dumb question!
